Podocarpaceae - Podocarpus L'Hér. ex Pers.

Description:

  • Trees or shrubs, dioecious, evergreen
  • Leaves spirally arranged, subopposite or whorled, rarely opposite, linear to narrowly ovate or scale-like, long-persistent
  • Male cones usually consisting of many fertile scales, each bearing 2 pollen sacs, axillary, rarely terminal, sessile to shortly stalked, catkin-like, solitary or in groups of 2-5; pollen grains usually with 2 air-bladders or wings
  • Female cones axillary, on thin naked stalks or on short leafy or scaly branches, usually reduced to 1 or 2 fertile, terminal scales and a few sterile, lower scales fused with each other and with cone axis; fused cone axis and scales beneath seeds either remain woody or become swollen and often fleshy at maturity (receptacle)
  • Ovule solitary, adnate to face of fertile scale, inverted and enclosed in a false aril (epimatium) arising from face of scale and adnate to single integument
  • Seeds ellipsoid to globose; testa and false aril form a coriaceous or externally fleshy and internally ± woody shell; embryo axile; cotyledons 2
  • x = 13

Classification Notes:

  • De Laubenfels (1985) gives a description of infrageneric taxa, but no genus descriptions
  • Page (1990) places one southern Africa species: Podocarpus falcatus (Thunb.) R.Br. ex Mirb., in his genus Afrocarpus
  • See Leistner et al. (1995) for reasons why only one genus is recognised in this work

Nomenclature:

  • Podocarpus L'Hér. ex Pers.
    • Persoon: 580 (1807) name conserved

    • Leistner: 34 (1966)
    • Page: 340 (1990)
    • Von Breitenbach & Von Breitenbach: 133 (1992)

Distribution & Notes:
